GCPのGPU搭載インスタンスで [Errno 13] Permission denied: '/root/google_vm_config.lock'

背景

GCPのGCEのGPU搭載インスタンスで推論処理の入ったunicornプロセスを起動したところ [Errno 13] Permission denied: '/root/google_vm_config.lock' のエラーが発生

環境

• Debian GNU/Linux 11
• cuda 11.8
• bitsandbytes 40.2

やったこと

GOOGLE_VM_CONFIG_LOCK_FILE を .../bitsandbytes/cuda_setup/env_vars.py の to_be_ignoredn追記する

参考

私の環境では、env_vars.pyは以下のpathでした /home/USER_NAME/.local/share/virtualenvs/VIRTUAL_ENV/lib/python3.10/site-packages/bitsandbytes/cuda_setup/env_vars.py

from typing import Dict


def to_be_ignored(env_var: str, value: str) -> bool:
    ignorable = {
        "PWD",  # PWD: this is how the shell keeps track of the current working dir
        "OLDPWD",
        "SSH_AUTH_SOCK",  # SSH stuff, therefore unrelated

    }
    return env_var in ignorable
